vacuum Application filed June 3, 1921. Serial No. 174,6752.

various forms of nozzles and brushes may be used in connection with 'the suction for cleamng draperies, upholstery and the like. The objects of the lllVGll'tlOll'iLI'G to provide a vacuum cleaner with means for con 'necting an attachment,.of the character described, directly to thefan chamber of the cleaner, the attachment being adapted to be projected through the nozzle of the sweeper and into a suitable aperture in the fan chamber, means being provided for normally holding the attachmentin place after it has been inserted. Other objects are the provision of means upon the cleaner for raising the nozzle ofthe cleaner above the surface of the floor a sufficient distanceto allow the attachment to be inserted and operated conveniently.

The above, together with ancillary objects may be attained by providing an eccentric shaft or axle j ournaled in. suitable bearings near the forward end portionof the cleaner and.- carrying the traction wheels and by providing a suitable opening into the under wall of the fan chamber, the attachment comprising a curved tubuhir member arranged to be inserted tlnrough the nozzle of l the cleaner and provided. with a collar arrz'niged to be received in. said opening, a spring being provided for holding the at tachment in the o icrati've position, the outer end of the attaclnucnt being arranged to re eoive the usual nipple of the flexible hose to which. the usual nozzles and brushes .may be connected.

lVith these objects in view, the. invention consists inthc construction and arrangement of parts, hereinafter described and illus trated in the accompanying drawings, .it

being understood that various changes in the form and details of construction may be Fig. 2 is a section on the line 2-2, Fig. 1

Fig. is a section on the line 8-8, Fig. l; 4: is a section 011 the line t l-, Fig. 3 Fig, 5 is a detail sectional view of one of the traction wheels and a portion of the shaft showing the means for attaching the wheel to the shaft;

Fig. 6 is a perspective view of the attachmentshowing the under side thereof; and

Fig. 7 is'a perspective view of the upper side of the attachment.

Similar numerals of reference indicate corresponding parts throughout the several. figures of the drawings.

The sweeper comprises generally the case 1v having the usual nozzle 2, the fan chamber 3 and exhaust outlet 4 leading to the usual dust bag 5, a motor 6 of usual construction being mounted upon the case above the fan chamber and having operatively connected thereto the usual rotary fan 7 which is located within the fan chamber and arranged. to exhaust air from the nozzle into the fan chamber through the opening 8 provided in the lower wall 9 of the fan chamber.

All of these parts may be of any usual con struction, the operiingS, however, being of suitable size and shape to receive the extremity of the attachment, as will be later described, the front wall of the nozzle having the shallow recess 10 which.-accommodates the attachment. The usualrear wheel. 1']. is urovided upon the case and the forward. wheels 1,52 and. 1,3 are rotatably mounted upon. the eccentric shaft 14: which is journaled. in suitable bearings 15 and 16 mounted upon the e: se l... i j a The shaft 141: is provided at each end be yond the bearings-i, with the elf-set portions 17 upon which the wheels are journaled, a collar 18 being fixed upon each of these off set portions at a point spaced from the extreniity of the shaft, the wheel being journaled upon the shaft and prevented from having a tapped bearing portion 24 thereon through which is located the adjusting screw 25 arranged to engage the adj acent off-set portion 17 of the eccentric shaft, as shown 1n the dotted position in Fig. 4 for the purpose of holding the nozzle at the desired height above'the carpet.

The wheel 12' is provided with the peripheral groove 26 for the reception of a ,r'esilient belt 27 which is located over the pulley 28 upon the brush shaft 29. lVhen the eccentric shaft is in the position shown in Figs. 1, 3' and 4, itwill be seen that this resilient belt will tend to hold the shaft in this position, urging the front wheels toward the brush shaft. 7

When the cleaner is adapted to be operated over the floor in the usual manner,

theshaft is moved into the position shown in dotted lines in Fig. 4, the adjusting screw 25 engaging the adjacent off-set portion 17 v of the shaft holding the front wheels in the desired position, the nozzle of the cleaner being'thus held at the proper height I above the floor.

With the shaft in this position, it will be seen that asthe adjusting screw is moved downwardly to force the wheels downward, and raise the nozzle slightly above the floor, the tension upon the belt 27 will be increased, while as the parts are adjusted in the opposite direction, the tension upon the belt will be decreased. It will thus be seen that as the nozzle is adjusted away fromthe floor, such as is necessary for carpets having along nap, a greater tenslon will be placed upon the belt, preventing slipping of the belt, due to the friction of the brush upon the long nap of the carpet.

The attachment which is connected to the sweeper for the purpose of attaching the usual flexible hose, which carries the various nozzles and brushes for cleaning draperies,

, upholstery and the'like, is best shown in Figs. '6 and 7 and comprises the hollow curved tubular member indicated generally at 30 having the straight outer portion 31 adapted to receive the nipple 32 of the fleXible hose33'. v

The attachment is curved upwardly at its Y central portion as at 34 and'provided with the slightly flattened, rearwardly projected hose.

portion 35 having an annular opening 36 in its upper face, said opening being surrounded by the shouldered, annular flange 37 of suitable size and shape to fit snugly within the opening 8 in the fan chamber.

A substantially U-shaped wire spring 38 is connected at its extremities to the curved portion 34 of the attachment as by the screws 39, the legs of said spring being curved or bent away from the flattened under surface of the attachment as at 40, the bar 41. of the spring engaging the under surface of the attachment near the rear end thereof.

In connecting the attachment to the sweeper, the shaft 14 is moved into the position shown in Figs. 1, 3 and 4, raising the case of the sweeper a considerable distance above the floor, allowing easy access to the nozzle. The flattened end of the attachment is then inserted through the nozzle and the annular flange 37 is engaged with the opening 8 in the bottom wall of the fan chamber, the spring 38 engaging the bottom wall 42 of the ease and holding the attacle ment in engagement with the fan chamber, the straight portion 31 of the attachment extending through the nozzle and being seated in the shallow recess 10 in the front wall thereof.

The nipple 32 of the flexible hose may then be inserted into the straight end of: the attachment and any desired nozzle or brush placed upon the free extremity of the It will be seen that the flexible hose is connected directly to the fan chamber by means of the attachment above described.

The cleaner may be wheeled upon the floor to any desired point and the nozzle or brush upon the flexible hose may be easily operated therefrom. The attachment will be pivotally connected at the opening 8 and may be swung in either direction upon said pivot as shown in dotted lines in Fig. 2, the straight portion 31 of the attachment moving within the shallow recess 10 in the front wall of the nozzle of the cleaner, this pivotal movement of the attachment within the cleaner allowing for free movement of the flexible hose, without danger of overturning the sweeper.
